CONVEYER TItOLLEY-TRAGK AND TROLLEY THEREFOR.

Specification of Letters Patent.

Patented Apr. 1 0, 1917.

Application filed May 20, 1916. Serial No. 98,856.

To all whom it may concern:

Be it known that I, ARTHUR L. SHAW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Conveyer Trolley- Tracks and Trolleys Thcrefor, of which the following is a specification.

My invention relates to improvements in conveyer trolley tracks and trolleys therefor, whereby to transport or transfer heavy articles from place to place in the line of the track.

One of the objects of my invention is to provide a simple, sturdy, suspended track, and means for bodily swiveling the track at its pivotal points of suspension, whereby to permit it to have some lateral movement to accommodate itself to the changing lateral positions of the under-running load, to reduce resistance to the moving trolley and to maintain the weight of such loads equally on each side of the track and of the trolley moving thereon.

Another object of my invention is to provide convenient, simple and effective means for vertically adjusting parts thereof to maintain longitudinal alinement of the entire track.

Other and further objects of my invention will become readily apparent, to" persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is a perspective view of a trolley track and a plurality of supports from Which it is suspended.

Fig. 2 is a plan view of a fragment of the track.

Fig. 3 is a transverse section taken through the track and trolley.

Fig. 4 is a section taken on line 4-4: of Fig. 2.

In all the views the same reference characters are employed to indicate similar parts.

5 indicates a plurality of overhanging supports, which may be of any desirable character, from which my trolley track is to be suspended.

The supports 5 should overhang the vertical supports 6 sufficiently to permit plenty of room between the base of the support 6 and the vertical plane in which the trolley track is contained.

The track is composed of two angle-irons or bars 7 and 8, secured together by spacing blocks, 9, as by means of rivets 10, placed at sufficiently close intervals, to allow spaces between said angle irons and between said blocks, within which to contain the track hanger. The vertical legs of the angle irons 11 and 12, respectively, are located in juxtaposition, with the legs 13 and 14, respectively, extending outwardly, or at sub stantially right angles thereto upon which to support the trolley 15. j

A series of bolts lb, each having an eye or book 17 at one end, and screw threaded, as at 18, atthe other end, pass through the support 5 and are secured in adjusted position by the nuts 19 and the set nuts 20. A series of similar bolts 21, are each provided with an eye 22 at one end and is screw threaded, as at 23, at the other end, the latter end passing through the interspace between the vertical legs 11 and 12 of the respective angle-bars, and may be located at any desirable position between the space blocks 9 and at suitable intervals, to support the track. A nut 24: is screwed on the end of each of the bolts 21, and the abutment, by which the track is supported and held in longitudinalposition by the bolts 21. The alinement of the track may be varied by changing the position of the nuts 24 or by raising or lowering the nuts 19 and 20 on the bolts 16, or by the use of the nuts on each or both of the bolts. The supporting bolts 21 may be placed anywhere between the distance blocks 9, so that when the bolts 16 are in position the bolts 21 may readily and easily be shifted in the trolley track to correspond with the positions of the bolts 16.

Fig. 1 shows the track suspended in the same vertical plane as that in which the points of suspension are contained, while Fig. 3 shows the track moved laterally from the said vertical plane on its pivotal supports and visually indicates that the load is equally distributed upon the respective sides of the track and trolley.

The trolley consists of two plates-25 and 26, each plate carrying a pair of trolley wheels 27. The two plates are brought together and riveted, as at 28, at the bottom, where they are perforated, as at 29, to receive the hook 30 of the pulley block 31.

My improved track and trolley a're especially adapted for moving coal conveyers from car to car along the railway side track, substantially as disclosed in my copending application filed of even date herewith, Serial Number 98,855. i

In the use of such conveyers the load suspended from thetr olley track is frequently located some distance from the vertical planeof suspension. It, is, therefore, very advantageous to have the track pivotally secured, as herein disclosed, so as not to im pose the greater part of the load upon one of therails of, the track and the wheels on that-side of the trolley. The lateral swiveling'movement of the track and trolley furthermore contribute to the easy running of the trolley and to the certainty of its operation and position.

Having described my invention, what I claim is 1. A swinging trolley track comprising two parallel angle bars having two of their vertically disposed confronting flanges held together in spaced-apart relation at suitable intervals, the out-turned flanges of said bars in a. horizontal plane providing the trolley support of the track; eye bolts having their threaded shanks longitudinally adjustable in the. space provided between the bars and having nuts on their threaded shanks adj a- Gopies of this patent may be obtained for five cents each, by addressing the cent the lower edges of said vertical flanges whereby to vertically adjust the track at suitable intervals, and similar bolts having eyes or hooks for engagement with the eyes of the track bolts and having adjustable check nuts whereby to vertically adjust and fix said bolts in adjusted positions.

2. In combination with spaced apart angle bars to provide a trolley track, of substantially rectangular perforated spacing blocks, 9, substantially as wide as the In testimony whereof I hereunto set my 5 hand in the presence of two subscribing witnesses.
